Description

Technical Field

[0001] The utility model relates to the field of supporting structures, in particular to a supporting structure for installing a gate valve cylinder of an extruder. Background Art

[0002] Extruder is a type of plastic machinery. The die head can be divided into right-angle die head and bevel die head. When using the extruder, it needs to be used with a gate valve. The function of the gate valve is to block the processing raw materials and allow the raw materials to flow. The gate valve includes a valve body and a barrel, and the barrel needs to be installed on the material pipe of the extruder.

[0003] The diameter of the extruder's material pipe is large, and the gate valve that needs to be used with it also needs a barrel of the same diameter. The barrel is not only large in diameter but also heavy. During the installation process, multiple people are required to cooperate in lifting the gate valve so that the barrel of the gate valve and the extruder's material pipe are aligned, which makes installation inconvenient and difficult.

[0004] In order to solve the above-mentioned problems, we propose a support structure for installing a cylinder of an extruder gate valve. Utility Model Content

[0005] The utility model aims to provide a support structure for installing a gate valve cylinder of an extruder, which has the advantage of being able to support the gate valve cylinder when the gate valve is installed.

[0006] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a support structure for installing a cylinder body of an extruder gate valve, comprising a base, a guide groove is provided on the top of the base, two connecting seats are slidably connected inside the guide groove, a threaded rod is rotatably connected inside the connecting seat through a bearing, a nut is threadedly connected to the surface of the threaded rod, a support rod is fixedly sleeved on the surface of the nut, a connecting plate is installed on the top of the support rod, a support seat is provided on the top of the connecting plate, a driving motor is installed on the top of the connecting seat, two support plates are provided inside the base, a rotating rod is rotatably connected inside the support plate through a bearing, two bevel gears 1 are fixedly sleeved on the surface of the rotating rod, the output end of the driving motor is fixedly connected to a connecting rod through a coupling, and the surfaces of the connecting rod and the threaded rod are fixedly sleeved with bevel gear 2; an electric cylinder 1 and an electric cylinder 2 are also respectively provided inside the base, and the output ends of the electric cylinder 1 and the electric cylinder 2 are respectively fixedly connected to the two support plates.

[0007] By adopting the above technical scheme, the support of the gate valve during installation can be achieved by arranging a base, a guide groove, a connecting seat, a threaded rod, a nut, a support rod connecting plate and a support seat, eliminating the need for manual lifting and reducing the difficulty of gate valve installation. Under the action of the drive motor, the connecting rod, the rotating rod, the bevel gear one, the bevel gear two and the threaded rod, the nut and the support rod, the height of the supported gate valve can be adjusted. Under the action of the electric cylinder one, the electric cylinder two and the two support plates, the distance between the two support seats can also be adjusted, so that the support structure can support gate valves of different sizes.

[0008] The utility model is further configured as follows: a sliding groove is provided on the top of the connecting plate, a sliding block fixedly connected to the support seat is slidably connected inside the sliding groove, a plurality of clamping grooves are provided on one side of the sliding block, and a limiting screw clamped with the clamping groove is connected to the internal thread of the connecting plate.

[0009] With the above technical solution, the slide groove and the slider are used to guide the movement of the support seat, and the limit screw is used to engage with one of the multiple slots to fix the position of the slider.

[0010] The utility model is further configured as follows: surfaces of the two first bevel gears are respectively meshed with the two second bevel gears.

[0011] By adopting the above technical solution, through the meshing of bevel gear 2 and bevel gear 1, when the driving motor drives the connecting rod to rotate and drives the bevel gear 2 on the surface of the connecting rod to rotate, the bevel gear 2 on the surface of the connecting rod will mesh with a bevel gear 1, thereby driving the bevel gear 1, the rotating rod and the other bevel gear 1 to rotate.

[0012] The utility model is further configured as follows: through grooves are provided inside the two support plates, and the interiors of the two through grooves are respectively sleeved with the first electric cylinder and the second electric cylinder.

[0013] By adopting the above technical solution, through the setting of the through grooves, the two through grooves are respectively opened inside the two support plates and are respectively mounted on the electric cylinder one and the electric cylinder two. When the electric cylinder one and the electric cylinder two respectively push the two support plates and the structure connected to the support plates to move, the movement of the two support plates will not be blocked by the electric cylinder one and the electric cylinder two.

[0014] The utility model is further configured as follows: two fixing plates are fixedly connected to the bottom of the inner cavity of the base, and the interiors of the two fixing plates are fixedly connected to the surfaces of the first electric cylinder and the second electric cylinder respectively.

[0015] By adopting the above technical solution, through the setting of the fixing plates, the two fixing plates are respectively used to support and limit the electric cylinder 1 and the electric cylinder 2.

[0016] The utility model is further configured as follows: two guide grooves are arranged inside the support rod, and guide rods fixedly connected to the connecting seat are slidably connected inside the guide grooves.

[0017] The above technical solution is adopted to provide the guide groove and the guide rod for linear guidance and position limiting of the support rod, so as to prevent the support rod from rotating along with the threaded rod.

[0018] The utility model is further configured as follows: a universal wheel is installed at the bottom of the base.

[0019] By adopting the above technical solution and setting the universal wheel, the structure can be easily moved after lifting the gate valve.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model can support the gate valve for installation by arranging a support seat, a connecting plate, a support rod, a threaded rod, a nut, a connecting seat, a guide groove and a base, thereby avoiding manual lifting of the gate valve, reducing manual physical strength for lifting the gate valve for a long time, reducing the difficulty of installing the gate valve and providing convenience for the installation of the gate valve;

[0022] 2. The utility model is provided with a driving motor to drive the connecting rod, the second bevel gear, the first bevel gear, the rotating rod and the threaded rod to rotate. The rotation of the threaded rod can drive the nut to drive the support rod and the connecting plate and the support seat at the top thereof, as well as the gate valve supported by the top of the support seat to adjust and move up and down, thereby meeting the installation support requirements of the gate valves at different heights;

[0023] 3. The utility model respectively connects two support plates by setting electric cylinder one and electric cylinder two. The electric cylinder one and electric cylinder two can push and pull the two support plates and the structure connected to the support plates closer to and away from each other, so that the distance between the two support seats can be adjusted, thereby facilitating the structure to adapt to gate valves of different sizes for installation and support.

Through the meshing of the bevel gear 2 14 and the bevel gear 1 12, when the driving motor 9 drives the connecting rod 13 to rotate and drives the bevel gear 2 14 on the surface of the connecting rod 13 to rotate, the bevel gear 2 14 on the surface of the connecting rod 13 will mesh with a bevel gear 1 12, thereby driving the bevel gear 1 12, the rotating rod 11 and the other bevel gear 1 12 to rotate.
